Detailed Implementation
[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1
[0035] Please see Figures 1-4 The waste collection bin shown in the figure includes a bin body 1 with multiple casters 2; a handle 3 and multiple first protective plates 4; an extension assembly 5, which is used to spread the multiple first protective plates 4 to protect the bin body 1 while allowing the casters 2 to move up and down; a control assembly 15, which controls the extension assembly 5 to operate via the movable handle 3; and a movable assembly 26, which is used to cooperate with the telescopic assembly to drive the extension assembly 5 to operate.
[0036] Please see Figures 6-7The extension assembly 5 shown in the figure includes a second protective plate 6 located between two first protective plates 4, a third protective plate 7 located between the second protective plate 6 and the first protective plate 4, two meshing first gears 8 rotatably connected to the top of the third protective plate 7, a first connecting rod 9 rotatably connected between the second protective plate 6 and the third protective plate 7, the end of the first connecting rod 9 being fixedly connected to the central shaft of the first gear 8, a second connecting rod 10 rotatably connected between the third protective plate 7 and the first protective plate 4, a caster wheel 2 rotatably connected to the bottom of the third protective plate 7, a third connecting rod 11 rotatably connected to the third protective plate 7, a rotating shaft 12 rotatably connected to the end of the third connecting rod 11, a fourth connecting rod 13 rotatably connected to the first protective plate 4 rotatably connected to the rotating shaft 12, a fifth connecting rod 14 rotatably connected to the second protective plate 6 rotatably connected to the rotating shaft 12, and the first protective plate 4 located at the outermost end being fixedly connected to the housing 1.
[0037] Please see Figures 3-5 and Figure 8 The control component 15 shown in the figure includes a movable rod 16 that is fixedly connected to the handle 3. A first movable groove 17 that moves with the handle 3 is provided on the housing 1. A second movable groove 18 that communicates with the first movable groove 17 is provided inside the housing 1. The movable rod 16 moves within the second movable groove 18. A connecting rod 19 is rotatably connected to the second protective plate 6. A sliding groove 20 that slides with the connecting rod 19 is provided on the housing 1. A connecting component 21 is provided between the connecting rod 19 and the movable rod 16.
[0038] The first movable groove 17 is fitted with two mutually pressing rods 35, which press against each other. The pressing rods 35 press against the handle rod 3, and the pressing rods 35 are connected to the box body 1 by a second compression spring 36. Multiple L-shaped limiting plates 37 that are engaged with the first protective plate 4 are fixedly connected to the box body 1, and a fourth protective plate 38 is fixedly connected to the end of the box body 1.
[0039] Furthermore, the height and length of the first protective plate 4, the second protective plate 6, and the third protective plate 7 are the same. The top of the third protective plate 7 in the extended state is level with the top of the first protective plate 4. The top of the handle 3 is made of rubber, and the end of the pressure rod 35 is at an inclined angle.
[0040] In this embodiment, the box 1 is placed on the road surface. At this time, the height of the caster wheel 2 is higher than the bottom of the box 1. The caster wheel 2 does not contact the ground, while the box 1 contacts the ground, thus ensuring the stability of the box 1 and preventing movement. Then, the handle rod 3 is held and lifted upward along the first movable groove 17. The movable rod 16 moves along the second movable groove 18. Under the action of the connecting component 21 and the movable component 26, the connecting rod 19 moves along the sliding groove 20, thereby moving the second protective plate 6. The moving second protective plate 6, under the action of the two meshing first gears 8, the first connecting rod 9, and the point connecting rod, causes the first protective plate 4, the second protective plate 6, and the third protective plate 7 to expand away from each other.
[0041] The third connecting rod 11, the fourth connecting rod 13, and the fifth connecting rod 14 cooperate with each other to move the third protective plate 7 downward, thereby moving the caster wheel 2 downward and lifting the box 1. This makes it easier to move the box 1 by pulling the handle rod 3 and tilting the box 1, causing the caster wheel 2 to rotate.
[0042] The top of the handle 3 has a U-shaped structure, which makes it easy for the operator to choose to move the box 1 by lifting or dragging.
[0043] Example 2
[0044] This second embodiment is a further supplement and explanation of the first embodiment. Please refer to [link / reference]. Figures 8-10 The connecting component 21 shown in the figure includes a second gear 22 that rotates inside the housing 1. Above the second gear 22, there is a vertically movable toothed plate 23 that engages with the second gear 22. A first compression spring 24 is connected between the toothed plate 23 and the housing 1. The end of the movable rod 16 is rotatably connected to a vertically movable toothed plate 25, which meshes with the second gear 22. Both ends of the toothed plate 25 are smooth sections.
[0045] In this embodiment, when the handle 3 and the movable rod 16 move upward, they drive the toothed plate 25 to move vertically upward. The toothed plate 25 drives the second gear 22 to rotate, thereby causing the movable component 26 to operate and thus moving the second protective plate 6. At this time, the smooth section of the toothed plate 25 engages with the second gear 22. Then, the handle 3 is rotated to tilt it, making it easier for the user to pull the box 1 and move the box 1. At this time, the toothed plate 25 remains stationary and does not drive the second gear 22 to continue rotating. Under the action of the first compression spring 24, the non-rotating second gear 22 causes the locking plate 23 to lock the second gear 22, keeping the second gear 22 stable and stationary, thereby ensuring the stability of the unfolded first protective plate 4, second protective plate 6, and third protective plate 7.
[0046] Example 3
[0047] This third embodiment is a further supplement and explanation of the second embodiment. Please refer to [link / reference]. Figures 8-10The movable component 26 shown in the figure includes a first rotating wheel 27 and a second rotating wheel 28 that rotate within the housing 1. The second rotating wheel 28 is fixedly connected to the central shaft of the second gear 22. A first conveyor belt 29 is rotatably connected to the outer surfaces of the first rotating wheel 27 and the second rotating wheel 28. A fixed rotating wheel 30, which is sleeved on the central shaft of the second rotating wheel 28, is fixedly connected inside the housing 1. A first rotating rod 31 is fixedly connected to the end of the central shaft of the second rotating wheel 28. A third rotating wheel 32 is rotatably connected to the end of the first rotating rod 31. A second conveyor belt 33 is rotatably connected between the fixed rotating wheel 30 and the third rotating wheel 32. A second rotating rod 34, which is fixedly connected to the central shaft of the third rotating wheel 32, is fixedly connected to the connecting rod 19.
[0048] In this embodiment, when the second gear 22 rotates, it drives the second rotating wheel 28 to rotate, which in turn drives the first rotating rod 31 to rotate, thereby causing the third rotating wheel 32 to perform circular motion. Under the action of the fixed rotating wheel 30 and the first conveyor belt 29, the third rotating wheel 32 rotates, thereby driving the second rotating rod 34 to rotate, causing the connecting rod 19 to slide along the sliding groove 20 from one end to the other end, so that the first protective plate 4, the second protective plate 6, and the third protective plate 7 can spread out.
